Oct. 4, 1932. D. H. BITNEY INSERT ANCHOR Filed July 28 1950 ENTOR TTORNE VS j. Hague Patented Got. 4, 1932 UNITED STATES DEWEY H. BITNEY, OF ALBION, MICHIGAN, ASSIGNOR TO UNION STEEL PRODUCTS PAT COMPANY, OF ALBION, MICHIGAN v 5 INSERT ANCHOR Application filed. July 28,

The main object of this invention is to provide an insert anchor, that is an anchor which may be embedded in concrete, to facilitate the attachment thereto of an anchored part,

moved.

A still further object is toprovide an in-.

'sert anchor having these advantages which is very economical to produce and convenient to use.

Objects pertaining to details and econoinies of my invention will definitely appear from the description to follow. The invention is defined in the claim..

A structure which embodies the features of my invention is clearly illustrated in the accompanying drawing, in which:

Fig. 1 is a perspective view of my insert anchor.

Fig. 2 is a fragmentary section of a form illustrating the manner of positioning to receive the concrete.

Fig. 3 is a fragmentary view illustrating the position of the anchor in the concrete body and onemethod of attaching a part to he supported thereto, the part supported being indicated as metal lathing and the tie member being shown by dotted lines.

Fig; 4 is a fragmentarysection on line 4.l: of Fig. 3.

My improved anchor insert in the embodiment illustrated comprisesa plate-like body 1 having oppositely disposed flanges 2 on its longitudinal edges. These flanges are notch ed or recessed at 3. A hole 4 is also formed in the body to receive the concrete and thereby efl ect a more secure anchorage. The notched flanges also increase the anchorage so that even though the unit be made quite small it is effectively retained whenembedded in concrete as indicated at 5 in Figs. 8 and 4.

A flat tapered tang 6 projects from the outer end of the body member and is adapted 1930. Serial No. 471,187.

limit the penetration of the tang and also 7 serve as bracing members so that the device s not likely to be bent over in the event it is struck by some object. These stop shoulders also insure auniform amount of projeczion when the form is stripped.

The tang has a hole 9 adapted to receive a tie or attaching member 10 for attaching the object to be supported, such as metal lathing shown at 11 in Fig. 3. v

My improved insert anchors may be very economically produced and have a large,

holding capacity in proportion to size. The tangs should be driven into the forms parallel to the grain and may be very accurately positioned to receive the concrete.

I have not attemptedto illustrate certain modifications or adaptations for particular uses which Icontemplate as it is believed that this disclosure will enable those skilled in the art to embody or adaptthe same as may be desired.

' Having thus described my invention what I claim as new and desire to secure by Let-. ters Patent is:

An anchor for concrete comprising a platelike body portion adapted to be embedded in concrete, and flanges on its longitudinal edge, and a tang-like extension at one endadapted to be driven into a form, the ends of said flanges constituting form engaging stops, said plate having an opening therein, said tang being exposed when the form is removed and having an opening therein to facilitate attachment of an anchored part thereto.

In witness whereof I have hereunto set my hand.
